Dahlia plant named &#39;KLEDH14045&#39;

ABSTRACT

A new  Dahlia  plant particularly distinguished by having yellow ray florets and a medium plant height, is disclosed.

GENUS AND SPECIES

Dahlia sp.

VARIETY DENOMINATION

‘KLEDH 14045’

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Dahlia, botanically known as Dahlia sp. and hereinafter referred to by the variety name ‘KLEDH14045’. ‘KLEDH 14045’ is a selection that resulted from an open pollination of the proprietary female dahlia variety ‘DH-2010-0329’ (unpatented) and an unknown male parent in August and September of 2010. Seed were collected from the open pollination and planted, with a single plant selected in Stuttgart, Germany in May of 2011 and subsequently named ‘KLEDH14045’. Initial terminal cuttings of ‘KLEDH14045’ were taken in May of 2011 in Stuttgart, Germany. ‘KLEDH 14045’ was found to reproduce true to type in successive generations of asexual propagation via terminal cuttings in Stuttgart, Germany.

SUMMARY

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Stuttgart, Germany.

1. Yellow ray florets; and

2. A medium plant height.

DESCRIPTION OF THE PHOTOGRAPHS

This new Dahlia plant is illustrated by the accompanying photograph which shows the overall plant habit of the plant grown in a pot. The plant is about 3 months-old grown in Stuttgart, Germany in April 2014. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘KLEDH14045’. The data which define these characteristics were collected from asexual reproductions carried out in Stuttgart, Germany. Data was collected on two month-old plants in April 2015, grown in a controlled greenhouse environment approximate to those generally used in commercial production in Germany, natural light, unpinched, with growth regulators DAZIDE® and CYCOCEL®.
